Radio

Radio is a technology that uses electromagnetic waves to transmit and receive audio signals over distances. It operates within the radio frequency spectrum and allows for real-time communication and broadcasting. Radio communication involves converting sound waves into electrical signals, which are then modulated onto radio waves for transmission. These waves travel through the air and can be received by radio receivers, which demodulate the signals back into sound.

Radio can refer to various forms of media, including music, news, talk shows, and other programming that is broadcast over AM, FM, or digital frequencies. It serves as a platform for communication, entertainment, and information dissemination and can be accessible through various devices such as radios, smartphones, and computers. Radio has played a significant role in global communication and culture since its inception in the early 20th century.
